Sherrlyn is a female member of the Fighting Foe Men. After the Great Wars ended and Eternia was left without a king, a group of renegade pirates as the Fighting Foe Men took over the Valley of Gnarl and all the surrounding territories. Spreading fear throughout the land, they built great machines like the Roton and Talon Fighter to terrorize the populace. Challenged and eventually defeated by a champion of the north, Vikor, the Fighting Foe Men were cast into a glacier and magically frozen for over five thousand years. Eventually, they were discovered by Hordak, who returned to Eternia and set them free in return for serving in his army during the Second Ultimate Battleground.
